What is the membrane fouling of spring water equipment?
- 2019-05-18-

The spring water equipment uses an anode resin to soften the source water. The main purpose is to allow the anode resin to absorb calcium and magnesium ions in the water.

The spring water equipment can reduce the hardness of the water source and recycle the recycled smart resin.

The safety filter is used to remove the residual suspended matter in the influent water, the non-curvature particles and the colloid, so that the subsequent equipment such as the ultrafiltration system can operate safely and stably. The filter element is a 5um meltblown filter. The purpose is to prevent the upper filter unit from removing impurities larger than 5 um. Prevents entry into the ultrafiltration unit and damages the surface of the membrane, thereby damaging the performance of the membrane.

The tap water pressure pump is used to increase the water supply pressure of the system. Multi-media filters remove suspended solids and impurities from the water. The activated carbon filter removes residual chlorine, odorous substances and odorous gases in the water to improve the taste. The precision filter further removes impurities from the water. The hollow ultrafilter removes harmful substances such as impurities, colloids, phenolic compounds, chlorides, bacteria, etc., and retains beneficial minerals in the water in the water.

Ultra-filtration membranes are used in mountain spring water equipment. The ultrafiltration membrane is a very fine element. When the raw water comes into contact with the ultrafiltration membrane, ultrafiltration membrane fouling has begun. Since the solute is adsorbed on the membrane, the membrane properties are changed to some extent. For the mountain spring water production equipment, if the ultrafiltration membrane is improperly selected, this will greatly affect the service life of the mountain spring water equipment.

Colloidal substances in the raw water, large molecular weight substances and particulate matter may chemically react with the ultrafiltration membrane, or mechanically interact, and then adsorb on the surface of the membrane, or precipitate on the membrane, thereby causing the pore size of the ultrafiltration membrane to become smaller or completely blocked. The molecular weight value of the ultrafiltration membrane is changed, which results in a decrease in the water quality of the spring water equipment.

Damage to the ultrafiltration membrane for a long time may result in the inability of the spring water equipment to be used. The important thing is that this process is an irreversible process.
